* | | lib: optimization of ringbufferDimitri Staessens2016-03-201-15/+14
| | | | | | | | | | | | | | | | | | | | | | | | Got rid of divisions and modulo operations. Change in the meaning of a #define. SHM_DU_MAP_SIZE: is now an exponent of 2. Default is 10, allowing for 1024 blocks in the map.
* | | lib: updated shm_du_map to be a hybrid ring bufferDimitri Staessens2016-03-193-171/+87
| | | | | | | | | | | | | | | | | | Elements must be created/destroyed in order, but IPCPs can access PCI while the PDU is in the ring buffer. Test updated, no more waits are needed.
* | | lib: shared memory mapDimitri Staessens2016-03-195-1/+830
|/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The shared memory map will allow passing SDU's between IPCPs efficiently. It is a single block of managed memory. SDU's are stored in a shm_du_buff datastructure, which is a list of blocks inside the shared memory region. The mechanism for passing SDU's is not yet implemented and could be either within the region or using another local IPC mechanism. The following things are configured at compile time: SHM_FILE_NAME : the name. Default is "ouroboros_du_map". SHM_DU_BUFF_BLOCK_SIZE: size of a block inside the shared memory region. Default is the pagesize of the system. SHM_DU_MAP_SIZE : the approximate size in bytes of the shared memory map. The actual filesize may differ by a small margin. Default is 4MB.
* / lib: fixes to du_buffDimitri Staessens2016-03-172-11/+18

* lib: Clean up memleaksSander Vrijders2016-03-171-4/+10
| | | | | Some allocations were not freed in case the creation of a new IPCP failed.
* lib: Add communication with IPCP daemonSander Vrijders2016-03-173-69/+387
| | | | | This adds the messages required for the IRMd to communicate with an IPC Process through the library.
* lib, irmd: Fix memleaksSander Vrijders2016-03-171-0/+1
| | | | | This removes some memleaks present in the sockets layer. It also fixes the bad initialization of the difs_size param in the irm_msg.

| * irmd, lib: Create and destroy IPC ProcessesSander Vrijders2016-03-154-22/+128
| | | | | | | | | | | | This adds the functionality to create and destroy IPCPs. Upon creation a new process is forked and execve'd. Upon destruction the IPCP is destroyed by killing it with SIGTERM.
* | lib: Updated du_buff not limit allowable PCI sizeDimitri Staessens2016-03-152-21/+30

| * lib: Add bitmap testSander Vrijders2016-03-093-26/+113
| | | | | | | | | | This adds a test for the bitmap. During the testing I also removed some bugs that were present in the bitmap implementation.
| * lib: Updated du_buff testDimitri Staessens2016-03-083-30/+3
| | | | | | | | | | | | Tests should have "_test.c" appended and include the source they are testing. The build system will find it in the parent directory. Removed linked_list example test as it is now useless.
| * tests: added test for the du_buff structureDimitri Staessens2016-03-083-1/+59
| | | | | | | | | | | | | | | | | | | | tests/du_buff.c: tests the du_buff_t structure by creating different size du_buff_t's and filling it with different size sdu's at different locations in the du_buff_t tests/CMakefile.txt: added du_buff test lib/du_buff.c: fixed unsafe #define adding brackets
* | lib: Add helpers for RINA namesSander Vrijders2016-03-116-35/+388
| | | | | | | | This adds helper functions for RINA names, to aid with handling them.
* | irmd, lib: Replace stubs in irmdSander Vrijders2016-03-094-1/+99
|/ | | | | | This replaces the stubs in the irmd and calls the actual IPCP operations from the library. It also calls the DIF Allocator API in one of the operations.

| * build: Add check target, fix packagingSander Vrijders2016-03-073-1/+49
| | | | | | | | | | | | | | | | | | This adds a build target 'check', which executes a test suite for every daemon/library. Every test suite consists of a test driver that executes a function in a file with the same name as the function. The compile_debug script executes the 'check' target to validate there are no regressions. Packaging is also fixed and the prototype can be shipped as a tarball.
| * build: Move debugging switch to correct CMakeListsSander Vrijders2016-03-031-0/+5
| | | | | | | | | | | | This moves the debugging switch down to the CMakeList associated with every program or library. It allows to build apps individually with debugging info on or off.

| | | | | | | This provides the other messages that are used to communicate between the library and the IRM Daemon. The IRM tool just calls the library right now to see if it works. A full fledged program will be provided in a next commit.

User can add compiler flag DU_BUFF_BLOCKSIZE to set the size of a du_buff memory block. If the size for the du_buff is larger than DU_BUFF_BLOCKSIZE, the du_buff will be structured as follows: HEAD -> DATA_BLOCK -> ... -> DATA_BLOCK -> TAIL HEAD and TAIL are contiguous and may be larger than DU_BUFF_BLOCKSIZE if required.
